In the form of the guide for the stays shown in Figsz 9 and1 0 the samecomprises two spring members 31 and 32 'fa'ste'nedto the upright" 17 Forforming 'aguidingcone the spring members 31'- and-32 are obliquely bentoutwards", so that-theoutwardlybent p'or tions" 33f and 34 togetherjwith the uprightli' form athjr'ee edged truncatedpyramidwhichconstitutes the cone proper for. guiding the stays.-The'free edges 35 0i? the springmembersaretouching each otherinordertoclose up-thecon'e.

n h 'form' shown in Fig. 11' he! guiding cone is -formedof a singlepiece of resilient sheet metal folded into the form of a three edgedprism. The'backportion of this guiding cone is secured to the upright 17for which purpose itis provided with holes 38 to admit screws. From theupper edge ofthe back portion 37 a blade 39 is bent downwards and fromthe lower edge of said back portion the blade .40 is bent upwards, theedges 410i said blades. touching each other to closeup the cone. Inorder that a laterally evading stay may securely be deflected intothecone i j the edges 42 of the blades37. 39 and lying on that side ofthe cone at which the stay enters. are bent outwardly in a trumpet-likefashion. I

' As soon as the stay has been shot through the whole of the width ofthe wire netting through all the guiding cones and twist limitcut offthe reel and this cut off portion of wire, which is the one insertedinto the cones and i the twist limiting members, is pushed forward bymeans of the uprights 17 and the guiding cones in the direction of thearrow 29, the stay being thereby pressed into the corner of the shed andleaving the twist limiting members 22, 23. If the thickness of the staywire, or theheight of its waves is greater than the distance of theedges 24 the latter will resiliently yield to the stay. ,The shaftsother by the strands 3 lying on the.blades 23,

the same thereby acting as a single edge:

At thetwisting together of the warps the same are also twisted togetherbehind the rear jaws 7, a second or. rear shed being thereby vided forthis purpose. This wind-up drum is described, together with the otherparts of the machine not described or:illustrated in thisspecification','ini the-said U. S. Patent No.783 ,832. I

' By this time the slide guiding cones returns to its rear position. Atthe returning of the guiding cones the stay 25 just pushed into thecorner of the shed must naturally remain in that position and as anecessity must depart from the guiding cones. In the form showni-n Figs.7 and 8 thislis efieotedthrough the swinging of the movable cone member13 into the position shown. in dotted lines in Fig. 7 In, the formsshown in':Figs. 9 and 10 the openingof the guiding cones is effected bythe edges 35 $01 the resilient blades 31 and 32, or '33 and, 34 movingaway from each other. 'In the form'shown in .11 the edges 41 are.resiliently opened inthe same manner as inthe form according to :Figs:9' and 10. The opening of theguiding' cones is effected bythe stayat therelative movement of stay and the slide 2. In. the

This iform of the limiting edges provides a greater securityagainst the slipping off ofthe warps from the blades23..

, In the forms of thetwisters above described each twisteri is providedwith'two edges24.

It should be noted however, that a single edge may be utilized as welland this may be provided either on anupper orona lower blade 23. I

Of the numerous modifications which may possibly be made within thescope of the. appended; claims it should be mentioned that the twistingjaws 6 and 7 may-alsobe made of a single piece in which case the pinsfor j ournalling the-rollers 1O and ll are inserted from outside throughbores in the jaws. and

in the rollers. The edges 24 for limiting the twisting together of thewarps may also be arranged. on rigid (non elastic) bladesfif themovability of the edges is assured by a pivotal arrangement; of therigid blades.
